##### 27.5.2.7 Assigning a computed title

If titles for your HTML pages can be determined based on the value of a macro variable, or on values obtained by expanding a macro, you can assign the macro or macro variable to the [HTMLOptions]Title keyword.

For example, to provide a page title that consists of the DITA source file name followed by an integer that increments for each HTML file generated:

    [HTMLOptions]
    Title=<$PageTitle>

    [PageTitle]
    <$$_basefile><$$PgNumber++ as %-0.3d>

    [MacroVariables]
    PgNumber=0

Any other title specification overrides a computed [HTMLOptions]Title value.
